Claims and Evidence

Improvements in symptoms of inattention have been shown after Cogmed training in groups with ADHD and other clinical diagnoses using behavioral rating scales (e.g. the inattention subscale from DSM-IV)

• The effect of training has been observed on improved parental ratings of inattention in ADHD children both immediately post Cogmed and at follow-up three months later (Klingberg et al., 2005).
• Data from 769 children collected pre and post-Cogmed at three distinct practices in Singapore, the Netherlands, and Canada has revealed that on average, Cogmed End-Users improved their inattentive symptoms, as rated on the DSM-IV Parent Rating Scale, by 30% from baseline to post-test. (Clinical Evaluation Series Part I).

• Children, mostly with ADHD, improved on the Inattention score of the Disruptie Behaviors Rating Scale by 33% at post-test, 42% at 6 months, and 40% at 12 months post-training. (Clinical Evaluation Series Part II).
